Clean freak Amy Winehouse

The 'Back to Black' hitmaker - who has previously battled drink and drug problems - has stunned friends with her fanatical attempts to keep her north London home spotless, but pals believe her new passion is good for her.

One source told Reveal magazine "Amy has become obsessed with cleaning and is spending hours every day polishing and scrubbing.

"It's an attempt to keep herself in check. So no one is trying to stop her from doing it.

"One of Amy's favorite things is to try out new cleaning products - she loves them. She literally spends hours scrubbing every inch of her home."

It was recently revealed Amy has had a huge clear out in her home and donated over £20,000 of clothes to charity.

A source said: "Amy turned up in a people carrier with loads of stuff in bin liners. Top, top designer gear.

"You'd imagine half of it would be covered in cigarette burns and smell of wild nights out but it was all in tip-top condition. Amy was joking with the shop girls that she has become addicted to cleaning.

"She has just moved house and said it was therapeutic getting her Marigolds on in just her underwear and having a clear out."
